* is not limited to use in the manufacture of this or of any particular class of footwear.

The machine of my invention includes a novel support upon which the sole and upper may be in proper relation preparatory to lastng the upper by overwiping the margin of its toe end upon the sole and securing the overwiped margin permanently in such position by the application of adequate pressure. It will be understood that the margin of the upper and the surface of the sole, or either of them, may be coated with an adhesive which acts, upon the application of pressure, to effect a permanent union between these parts of the shoe. As a convenient and effective means of maintainmg the sole in place onthe support, a suction opening or openings may be provided in the support and the sole held by suction within the projecting margin of the upper while the latter may be accurately located and held in the proper J po 'tion with reference to the sole. In using the machine of my invention for toe lasting, a support be employed having, as shown, an elongated or overhanging portion shaped to reach into the toe part of a shoe and adapted to en age and hold the toe end of the sole and to fill out the corresponding toe end of the upper. In one aspect, therefore, my invention consists in a machine provided with an elongated support having at its free end means for holding o the toe end of the sole by suction thereon, ar-

ranged in cooperative relation with means for laying the margin of an upper inwardly over the sole while the sole is so held.

A furthe feature of the invention consists in 3 a support arranged for movement from an outer the suction connections are broken or interrupted when the support is moved to its work-receiving position and are reestablished by the movement of the support to its operative position. This construction leaves the operator free to position the sole and upper upon the support in the first instance, with the assurance that the sole will be reliably held in such position without further attention on his part than may be required to present the work to the operation of the machine.

Preferably and as herein shown, upper clamping means are provided which are arranged to be brought into action when the support has been moved to its operative position. In order to position the support and the work against the thrust of such upper clamping means and also against the thrust of the wipers, means are provided for positively latching the support in its operative position and incidentally in the position in which the suction connections are effective for holding the sole thereon. Such construction constitutes a further feature of the in vention and contributes in adapting the machine for power operation with the development of adequate pressure and speed.

The support herein shown is mounted not only for transverse movement in the manner explained but also for movement heightwise of the shoe in order to subject the overwiped margin of the upper and the sole to adequate pressure to cause the adhesive to form a permanent union between the parts of the shoe. The desired results are effected by mounting the support or jack upon a vertically-movable carriage which is arranged to have its position controlled by suitable cam mechanism. The suction connections to the support are also contained to some extent in the jack carriage and the transverse movement of the support upon its carriage is utilized to interrupt and reestablish the effective connection between an air pump and the suction opening or openings of the support.

These and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof, selected for purposes of illustration and shown in the accompanying drawings, in which Fig. 1 is a view of the machine in side elevation as seen from the left;

Fig. 2 is a view of the head of the machine, on an enlarged scale, in side elevation as seen from the right, a portion of the frame being broken away;

Fig. 4 is a view in longitudinal section on the line IV-IV of Fig. 3; and

Fig. 5 is a view in perspective of a shoe which has been operated upon by the illustrated machine.

My invention is herein illustrated as embodied in a machine which is in some respects of the same general type as disclosed in my copending application Serial No. 629,514, filed August 19, 1932. For convenience, certain mechanisms which serve as well in one machine as in the other are identical in their construction and for a disclosure of details not fully shown herein reference may be had to said copending application. It will be understood, however, that the invention herein disclosed is in no sense limited to machines of this particular type but is applicable to end lasting machines in general. It will be understood also that while the illustrated machine is adapted for toe end lasting, it could with slight modification in its work-supporting elements be adapted for heel-seat lasting.

The head frame of the machine is supported at a convenient height by a suitable column and comprises a pair of vertically-disposed parallel side members connected at their upper ends by a transversely-disposed cover or top plate 11. The top plate 11 is secured to the head frame 10 by suitable bolts and clamped between it and the top of the side members on each side of the frame is a guide bar 12, these cooperating to form guides for a horizontally-movable wiper slide 13.

A pair of swinging wiper carriers 14 is mounted beneath the forward end of the wiper slide 13 upon a downwardly-extending pivot pin and wiper plates 16 are detachably secured to the forward edges of these carriers 14. The forward and rear portions of each wiper carrier 14 lie on the same side of the axis of the pin 15 and the wiper plates 16 are, accordingly, closed when the rear ends of the wiper carriers are separated. The wiper plates 16 may be shaped in contour to correspond to the particular footwear to be operated upon and are arranged to swing about the axis of the pivot pin 15, which coincides substantially with the center point in the margin of the toe. Each of the wiper carriers 14 is provided with an oblique cam slot 17, in which is received a cam roller 18 mounted upon a bolt 19 projecting downwardly through one of the guide bars 12. The axes of the rolls 18 are stationary and, consequently, when the wiper slide 13 is advanced, the rear ends of the wiper carriers 14 are swung outwardly and the working stroke imparted to the wiper plates 16. As shown in Fig. 3, the wiper slide occupies its forward position and the wiper plates 16 have completed the operation of overwiping or overlaying the margin of the up per, these plates being of such lengths as to act on the upper substantially as far rearwardly as the ball line of the shoe.

Reciprocation from front to rear is imparted to the wiper slide 13 by a cam lever 21 which, at its upper end, is received between ears projecting downwardly from the lower face of the wiper slide. The cam lever 21 is journaled to swing upon a transverse fulcrum shaft 22 extending between the sides of the head frame 10. At its lower end it is provided with a cam roller 23 arranged to run upon the periphery of a disk cam 24 fast upon a cam shaft 25 mounted in bearings in the side members of the head frame 10. The cam roller 23 is maintained in contact with the periphery of the cam by a tension spring 26 secured to the lower arm of the cam lever 21 and to a transverse pin 27 which extends across the head frame between its two side members.

The work to be presented to the wipers above described may be supported on a gooseneck jack 33 which is pivotally mounted by a transverse pin 34 extending between the sides of a head 32 comprising a part of the jack carriage 31. The jack carriage is mounted for vertical movement in ways formed partly in the head frame 10 and partly in a vertical cover plate bolted to ihe front thereof. The jack 33 is shaped so that it may enter and support the toe portion of a shoe and is provided at its free end with a toe plate 35 detachably secured thereto by an attaching screw 36. The contour of the toe plate corresponds to the outline of the insole to be employed and it will be apparent that toe plates of various shapes may be made available as the requirements demand.

The toe plate 35 herein shown is provided with suction openings by which the sole of the footwear may be temporarily secured in lasting position. To this end, the upper surface of the toe plate is provided with a marginal groove 3'7 with which communicate a series of transverse or radially-extending grooves 38, all of which lead to a centrally-disposed hole 39 extending through the body of the toe plate. A suction tube 40 is secured to the inner edge of the jack 33, passing upwardly through the free end thereof in alignment with the hole 39 in the toe plate, as shown in Fig. 4, and forming a substantially air-tight connection therewith. The tube 40 is curved to conform substantially with the inner edge of the jack 33 and is provided at its lower end with a reverse bend leading into the rear face of the jack behind its pivot pin 34. The lower end of the tube 40 communicates with a vertical bore 41 within the body of the jack which opens through its lower face in position to register with the upper end of an inclined air passage 42 extending downwardly and outwardly through the body of the head 32. A second suction tube 43 is connected to the lower end of the passage 42 and this extends rearwardly to an air pump 44 mounted at the rear of the head frame 10 and arranged to be continuously operated by means which will presently be described. The action of the pump 44 is to maintain suction throughout the system above described so that a vacuum will be immediately created in the grooves 37 and 33 of the toe plate whenever a sole is placed upon the toe plate. In this manner the sole is held firmly in the desired position and maintained in such position against displacement in the overwiping operation.

The jack 33 is pivotally mounted in the jack carriage to facilitate presentation of the work to the machine and to permit it to be swung from an outer or work-receiving position, indicated in dash lines in Fig. 2, to an inner or operative position, indicated in the same figure by full lines. A tension spring 45 extending between the rear end of the jack 33 and a portion of the head 32 of the jack carriage tends at all times to swing the jack forwardly into its operative position. In this position the lower end of the vertical air passage 41 is brought into substantially air-tight connection with the upper end of the inclined air passage 42 in the jack carriage and the suction of the air pump 44 is effective at the surface of the toe plate 35. When the jack 33 is swung outwardly against the tension of the spring 45, the air connection is broken at this point and there is no effective suction at the surface of the toe plate.

In order to maintain the jack 33 against acciental displacem nt from its operative position, the lower branch thereof is provided with an abut- -nt block 46 and with this cooperates a latch e e7, notched at its upper end to receive the so, and pivotally connected at its lower end e 32. A. tension spring 48 tends to swing atch piece a? always toward its engaging posi- The latch piece may be conveniently disenaged by operating a curved sheet metal hand e 9 whi h is secured to its upper end and which Xtends upwardly in general conformity to the e of the jack 33. The handle &9 thus loat d where it is naturally engaged by the hand of the operator in grasping the jack to move it .ut of operative position. In some cases, as sugin Fig. 2, the handle 49 is disposed within e upper of the footwear upon th jack and i adapted to be conveniently operated under such conditions by pressure transmitted through the upper.

The lack carriage 31, as already noted, is mounted fo. limited vertical movement. Its position regulated and controlled by a bell crank lever 52. ,ournaled up n a transverse shaft 53 extending between the sides of the head frame 10. The free of the cam lever 52 is provided with a cam roller 54 arranged on the periphery of a disk cam which is pinned to the cam shaft 25, already mentioned. A tension spring 56, extending be t n the lower of the lever 52 and transverse pin 2'7, serves to maintain the cam roller 5 at all times in engagement with the peof the cam. The cam 55 is designed to ele ate the jack carriage sli htly, after the wipers have been to the end of their operstroke, for the purpose of subjecting the wiped upper material and insole to pressure 'ntain such pressure for the desired the machine cycle. The com 55 is to release the jack carriage at the concluthe pressure-applying step, permitting its itial position.

clamping band 68 is provided for consmoothly to the corn the curved marginal face of the toe plate The result is that wh n the slide 63 is advanced, the center of ti e toe hand is brought igly into engagement with the center of the r automatically conforming it to the con the plate. The jack 33 is latched posiositicn to withstand the thrust of the operation by the action of o e-n slide 63 is is i for; i

members thereof. The slide 63 is provided upon its lower face with a swivel head 66 which connected through a substantially horizontal link 67 with the upper end of a lever arm 58 pinned to the shaft 22, which has already been described as serving as the journal for the wiper slide cam lever 21. At an intermediate point, the arm 68 is provided with a swivel head through which extends an operating rod 69. A compression spring Isl, interposed between this head and a nut on the oi the rod 69, supplies a yielding connection between the two. At its forward lower one. the operating 69 is connected to the upper e of an arm "21 pinned to the inner end of a sverse shaft 72 which is journaled in a boss outwardly from the left side member At the outer end of the ost motion connection with the upper end of a treadle rod 75 connected at its lower end to treadle 76. A tension spring 74 normally acts to elevate the arm '73 and the treadle and to rock the shaft 72 in a counter-clockwise direction. I wnl be that upon depressing the tread gala.

in its 76 is have their working stroke overwiped the margin of the upper the toe, the upper is, of course, held securely in place upon the toe plate and there is no further necessity for maintaining the clamping band in its forward position. trip the machine and the timing of the machine is such that the toe wipers engage th upper in their woi "1g stroke while the upper is still clamped by the toe band 60. machine is brought to rest automatically with the toe wipers y in their forward position, as shown in Fig. 3, whether or not the treadle is released. liowever, in order to restart the machine for the second portion of its cycle, the treadle must be re leased and the clamping band is, accordin ly,

retracted at that time to its initial position by the action of the spring 74, as shown in Fig. 1.

The main shaft of the machine may be driven from any convenient source of power and, as here with a roller or Horton clutch of which the driving member includes a sprocket wheel 85. The sprocket wheel driven by a sprocket chain as from a reducing gear unit 82 mounted upon a bracket 83 extending rearwardly from the head frame it. The reducing gear unit 82, in turn, is belt driven from a motor 8G supported upon a bracket 81 fast to the base of the column.

It is unnecessary here to describe fully the construction of the driving clutch since this is fully disclosed in my copending application above identified. It may be said, however, that associated with the driven member 86 is a roller cage having spaced projecting teeth 87 and 88 which are adapted to be engaged by a tripping dog 90 the shaft "72 will be rocked in a clock 1'3 The treadle 76 must be fully depressed to '1 shown, is provided upon its outer end latch piece 92 pivotally mounted upon a rearward extension of the arm '73, above mentioned. A tension spring 91 extending upwardly from the forward end of the clutch dog 90 urges the latter always toward its operative position for disengaging the clutch but when the treadle 76 is depressed, the latch piece is lifted and a tooth formed thereon engages the lifting pin 93 so that the clutch dog is lifted and the clutch permitted to engage. The latch piece 92 is disengaged from the lifting pin 93 as soon as the machine is set in operation by one or the other of two pins 94 which project endwise from the driven memoer of the clutch 86, and thus a non-repeating action of the clutch is insured.

The machine herein described may be employed with advantage in the manufacture of various types of footwear and, in order to render the manner of its operation clear, this will be outlined in connection with footwear of the gaiter or overshoe type, such as that shown in Fig. 5 of the drawings. This shoe comprises a flexible sole 190 reduced in thickness about its margin, thus providing a feather which it is the practice to coat with an adhesive cement. The upper 101 herein shown is of rubberized fabric and similarly provided with a band of cement about its margin. In Fig. 5 the shoe is represented. as having been operated on by the machine herein illustrated and in this process the margin 1'32 of the upper is overwiped about the toe portion of the sole and along the sides of the forepart and then subjected to pressure, so that the upper and sole are permanently united from the end of the toe substantially to the ball line of the shoe. The shank and heel-seat portions of the shoe are represented as having been lasted previously by the operation of the machine disclosed in my cop-ending application.

The construction of the machine and the manner of its operation will be more clearly understood from a summary of the successive steps carried out in producing the shoe shown in Fig. 5. Assuming that the machine is stopped by the engagement of the clutch dog 90 with the tooth 8"! and that the parts of the machine occupy their initial positions in the cycle, as shown in Fig. l, the motor 8-? may be assumed to be in motion and both the air pump as and the sprocket wheel 85 are being therefore operated. The operator may now grasp the jack 33, swinging the handle 49 to unlock the jack so that he may proceed to swing it outwardly into the dash line position shown in Fig. 2, wherein the toe plate 35 is conveniently exposed free and clear from all other parts of the machine and an opportunity afforded of conveniently placing the upper 12:1 in position with its margin conforming to the curved marginal face of the toe plate and projecting upwardiy the proper distance beyon the plane of the sole supporting face of the plate. The toe end of the sole may also be accurately positioned upon the toe plate within the projecting m rgin of the upper. As already explained, the suc ion connection to the toe plate is interrupted while the jack is in its work-receiving position on account of the separation of the lower end of the air passage 41 from the upper end of the air passage 42. Having brought the sole and upper into the desired relation under the convenient conditions explained, the operator may now swing the jack 33 inwardly, bringing the toe part of the shoe into range of the path of the toe wipers l6 and of the toe band 60. In this operation, the jack becomes locked in operative position by the action of the latch piece 47 and the suction connection to the toe plate is reestablished, whereupon the toe end of the sole is immediately held firmly by suction in place upon the upper surface of the plate. If the parts of the shoe are not properly positioned at this time, the operator may again unlock the jack and swing it outwardly for further adjustment, but if he is satisfied with the arrangement of the parts he may now proceed to depress the treadle '76.

When the treadle is depressed, the toe band 60 is first advanced through the connections above described and the margin of the upper is smoothly shaped and firmly clamped to the marginal face of the toe plate. In the continued depression of the treadle, the clutch is stripped and the shaft set in rotation. The wiper slide 13 is tl ereupon advanced by the action of the cam 24 and the connections above described and the wiper plates 16 are moved forwardly and inwardly with respect to the shoe, engaging the upstanding margin of the upper and over-wiping it upon the cemented feather surface of the sole 100. At substantially the conclusion of the advancing movement of the wipers, the cam 55 acts to elevate the jack and subject the sole and overwiped margin of the upper, which are now interposed between the toe plate and the wiper plates 16, to a substantial compression, thus causing the adhesive to form a permanent union between these parts of the shoe. In the continued rotation of the shaft 25, the clutch tooth 88 is engaged by the clutch dog 90 and the machine brought to rest with the work under pressure.

In most cases the machine may be immediately restarted after the work has been subjected to a momentary pressure but, if desired, the restarting of the machine may be delayed for an appreciable interval. When the treadle is new depressed for the second time, the toe band is advanced in an idle movement and the clutch dog disengaged from the tooth 88. The shaft 25 is thereupon further rotated and almost immediately the cam permits reverse movement of the cam lever 52 and lowering of the jack to initial position, thus releasing the pressure of the work against the wipers 16. When the pressure on the wipers has thus been released, the wiper slide 13 is moved rearwardly and the completed shoe may be removed from the machine after again releasing the jack 33 and swinging it outwardly.

The machine herein shown is equipped with of the gaiter type, it will be understood that my invention may be advantageously embodied in machines for use in the manufacture of footwear of other types including shoes of various kinds in which adhesive material is employed in the shoe bottom as a temporary or permanent upper-securing medium.
